Remarks: 1. The technical specification describes the ensured performance of the instrument when using typical PC model connector to measure. Without considering the uncertainty caused by optical fiber refractivity.

2. Dynamic range is the data measured under the condition of the maximum pulse width and 3 minutes of average time. Dynamic range is the data measured under the condition of **0km/****0ns/3min.

3. Measuring conditions of blind zone: reflection event is within 4Km, reflection strength < **5dB. Measured by the minimum pulse width.

4. Dynamic range measured when there is filter.

5. Dynamic range measured when there is no filter.
